Temperature in Second-Order Desorption Process

Question: Show that for a second-order desorption process the temperature at the peak maximum in the temperature-programmed desorption experiment is given by

(Hint: The surface coverage at the temperature corresponding to the peak has been shown by Redhead to be Γ_{0} /2.)

Solution: The rate of a second-order desorption reaction with surface coverage of Γ is given by,
